1 Claim. ((31. 20678) This invention relates to an improvement in bagsupportand deals. particularly with a card of paperboard or the like tovwhich a relatively flexible and pliable bag is-secured.

In the packaging of nut meats. and similar materials, it has become;common practice to seal these products in bags of cellophane or similarthinplastic or cellulosic materials. Where the bags are designedtosupport considerable weight, difiiculty is sometimes experienced inmounting the bags on a display rack or the like. Furthermore, it issometimes desirable to mount the. bags and their contents against acardboard backgound so that the contents show up more effectivelythanwouldotherwise be the case. In View of the fact that the; completeproducts are sometimes sold at an extremely low price, the. cards mustbe extremely inexpensive. Furthermore, for the same reason the cost ofmounting the bags upon; the cards must also be very low.

The. object of the present invention lies. in the provision of a card towhich a bag containing. a product may be mounted; The card is possessedof dimensionsv only slightly greater than the size of the bagso-that aminimum amount of paperboard is used.

A feature of the present invention resides in the provision of asupporting card for a bagged product which acts to conceal the majorportion of the bag ends. Bags of the type in question are often made bysealing the ends of a tubular bag body. In sealing the bag ends, the bagis often pressed between ribbed and heated dies which heat seal theopposite sides of the bag together. This ribbed and sealed end isusually made opaque by the.

sealing operation and is less attractive than the remainder of the bag.Furthermore, this sealed bag end is stronger than the remainder of thebag due to the fact that it comprises two plies of material securedtogether. Therefore by sealing the bag and by securing it through thesealed bag ends, a more attractive structure is provided and theresulting structure is stronger than would otherwise be possible.

A further feature of the present invention lies in the provision of acard support for bags and the like which require a minimum ofpaperboard. I provide one or more flaps cut from the body of the bag andfoldable out of the plane of the remainder of the card so that the flapsmay overlie the sealed bag ends. By inserting a staple or similarfastener through the bag and through the card, the bag may be supportedwith the sealed ends thereof concealed while at the same time the cardis only slightly greater in length and width than the bag itself.

A feature of the present invention lies in the simplicity of theconstruction. The flaps are so arranged that they may be folded out ofthe plane of the center portion of the card by merely folding the endsof the card at right angles to the body. When thus folded the spacebetween the flaps is suflicient to accommodate the entire bag. By thenfolding the flaps back toward the plane of the remainder of the card andby inserting a staple through Figure 3 is a perspective viewshowingtthe: bag support in position to receive the bag.

Figure 4 is a view ofadetail portion of a modified form of construction.

The bagsupporting card is indicated in general by the letter A and isdesigned to'support; a bagv B. The bagB is usually of the typeillustratedin-Figure 3 of the. drawings. and. includes a, generallytubularbody .10-haviu'g sealed-ends 11 and 12. The sealed ends 11 and12. are preferably produced by rolling the bags between. heat sealingrollers or: heat sealing; bars; although adhesive may be employed ifdesired.

The ends .11 and 1 2 ,of thesbagtbodry; are usually rendered. somewhatopaque. by thewhea-t sealing process and; are less-attractive than thebody of the bag. The bag bodyis. usuallytransparent-to,-cl'early-show'the bag contents. One; of the purposes. of; the presem:invention is-to-provide a-backing sheet; for the: bag which providesabetter: display of the. contents. At the, same, time, how:- ever, the.cardprovides; a simpktmeans. of advertisingthe product as weliaspother;products; it: isallsua'lly less expensive to print upon the paperboardcards than it-fs to: print; upon transparentbags; euiaeeordinghr'part ofthe. cost of; the-card is compensated for by the. lower price. oftheprint-ing operation.-

The: card A includes'a; fiatpard body,- 13: which extendssubstantially-the full length-ofwthe. bag: B..-. Aapairt of score lines14 extend inwardly in aligned relation near one end of the bag,separating a portion of the bag body from the card end 15. A generallyU-shaped out line 16 connects the inner ends of the score line 14. Thecut line 16 includes a pair of generally parallel cuts 17 and 19connected by a transversely extending out line 2!). This out line formsa tab 21 designed to overlie one end 12 of the bag B to be securedthereto.

In preferred form an car 22 is provided centrally of the tab or flap 21,this ear being formed by an undulation of the out line Zil. The ear 22lies beneath the bag or behind the bag, while the notch 23 formed in theflap 21 extends into this flap. A staple 24 may thus extend through theflap 21 on both sides of the car 22 and may extend about the ear 22 soas to hold the flap 21 substantially in alignment with the remainder ofthe card when the bag is in place.

The opposite end 25 of the card is similarly formed. A pair of alignedscore lines 26 and 27 extend into the card from opposite sides thereof.A U-shaped out line 29 connects the inner ends of the score lines 26 and27 and forms a fiap 30 designed to overlie the bag end 11. The cut line29 usually includes parallel side portions 31 and 32 and a transverselyextending out line 33 connecting the ends of the lines 31 and 32. Thetransverse out line 33 may be provided with an undulation 34 forming anear 35 which underlies the bag end 11. The corresponding notch formed inthe flap 30 brings into view a portion of the bag end 11. A staple 36may be inserted through the flap 30, the rear ends of the stapleclinching over the ear 35 to fasten the flap 30 substantially in theplane of the remainder of the card.

It is not essential that the staples 24 and 36 engage both thecorresponding flap and ear as the staples extend 3 through the bag andfasten the bag to the flaps 21 and 30, thereby holding these flaps insubstantial alignment. However, the ears do have the advantage ofreinforcing the staples and providing a better attachment with the bag.

In Figure 4 of the drawings, I disclose a modified form of card which isindicated in general by the letter C. Only one end of the card C isillustrated as both ends are similar in construction. In the card C, Iprovide a pair of U-shaped cuts 37 and 39 in side by side relation. Thecut 37 includes side portions it; and 41 and a transverse connecting cut42. The out line 39 similarly includes side portions 43 and 44 and atransverse connecting portion 45. All of the cut lines 46, 41, 43 and 44preferably terminate at substantially the same distance from the end 46of the card. Aligned score lines 47, 49 and 50 are provided extendingtransversely of the card. The score line 47 connects the out line 37 tothe side edge of the card, while the score line 50 connects the out line39 to the opposite edge of the card. The score line 40 connects the twoout lines 37 and 39. Thus the cut lines form inwardly projecting tabs 51and 52 beneath which the major portion of the bag end may be inserted.

The manner of attaching the bag B to the card A or B is illustrated inFigure 3 of the drawings. The ends 15 and 25 of the card A are foldedinto substantially right angular relation to the center portion 13 ofthe card. As a result the flaps 21 and 30 extend substantiallyvertically. This is usually done over a mandrel or stitching machinebody to simplify the operation. The bag B is next dropped onto the bodyof the card, the ends 11 and 12 lying inwardly of the flaps 30 and 21.The flaps are then folded back into substantially the plane of the cardbody and the staples are inserted at the proper location.

The card A or the card C will act to conceal the major portion of thebag ends and to hold the bags stretched tightly over the card surface.The card body may be printed to disclose the contents of the bag or toadvertise the contents or other products. The card need be of butslightly greater dimensions than the bag itself in order to function inthe manner described. The card C may be made slightly narrower than thecard A as the card C is provided with three lines of connection betweenthe central body portion and the end portions.

In accordance with the patent statutes, I have described the principlesof construction and operation of my bag support and while I haveendeavored to set forth the best embodiment thereof, I desire to have itunderstood that obvious changes may be made within the scope of thefollowing claim without departing from the spirit of my invention.

I claim:

A bag support for supporting a filled tubular bag having fiat sealedends, the support including a card having transverse cuts thereinadjacent the ends thereof defining a central body portion and two endportions hingedly connected to said central body portion along parallellines of fold, said transverse cuts extending inwardly from said foldlines and forming flap means on said end portions and foldable with saidend portions, said cuts also forming an ear extending outwardly fromsaid central body portion at each end thereof dividing the inner ends ofeach said flap means into two spaced flap portions, the flat ends of thebags overlying said central body portion and said ears and underlyingsaid flap means, and staple means straddling said ears and extendingthrough said spaced flap portions and said flat bag ends, and clinchedbeneath said ears.
